Critical Errors

OS/2 watches for physical errors during input and output operations. 
 Physical errors are those due to hardware problems, such as trying to 
read a floppy disk while the drive door is open. 

These errors are called critical errors because OS/2, CMD.EXE, or your 
application program cannot proceed until the error is resolved. 

When a critical error occurs, you will see a popup window asking you to 
choose one of four error handling options.  The message comes from OS/2 or 
CMD.EXE, and will vary slightly depending on whether you are in 
full-screen or windowed mode.  You can respond with a mouse click or menu 
selection.  The options and their meanings are similar in all cases: 

        Return error code to program.  Tell the program that the operation 
        failed.  This option returns an error code to CMD.EXE or to the 
        application program that was running when the error occurred. 
         CMD.EXE generally stops the current command when an operation 
        fails. 

        End program/command/operation.  Choose this option to stop the 
        program that was running when the error occurred and abort 
        CMD.EXE. 

        Retry command or operation.  Choose this option if you have 
        corrected the problem.
